{"abstract":"EPA is proposing partial approval of revisions to the prevention of significant deterioration (PSD) and nonattainment new source review (NSR) construction permit programs of the State of Indiana. On December 31, 2002, EPA published revisions to the federal PSD and nonattainment NSR regulations. These revisions are commonly referred to as \"NSR Reform\" regulations and became effective on March 3, 2003. These regulatory revisions include provisions for baseline emissions determinations, actual-to-future actual methodology, Plantwide Applicability Limits (PAL), Clean Units, and Pollution Control Projects (PCP). On June 24, 2005, the United States Court of Appeals for the District of Columbia Circuit issued its ruling on challenges to the December 2002 NSR reform revisions. Although the Court did uphold most of EPA's rules, it vacated both the Clean Unit and the PCP provisions. In addition, the Court remanded to EPA provision that requires recordkeeping and reporting for sources that elect to use the actual- to-projected actual emission test only where there is a reasonable possibility that a project may result in a significant net emissions increase. IDEM is seeking partial approval for rules to implement the NSR Reform provisions that have not been vacated by the June 24, 2005, court decision. This action affects major stationary sources in Indiana that are subject to or potentially subject to the PSD or nonattainment NSR construction permit program.","action":"Proposed rule.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2006/07/10/E6-10679.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"71 FR 38824","comment_url":null,"comments_close_on":"2006-08-09","correction_of":null,"corrections":[],"dates":"Comments must be received on or before August 9, 2006.","disposition_notes":null,"docket_ids":["EPA-R05-OAR-2004-IN-0006","FRL-8190-9"],"dockets":[],"document_number":"E6-10679","effective_on":null,"end_page":38831,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2006/07/10/E6-10679.xml","html_url":"https://www.federalregister.gov/documents/2006/07/10/E6-10679/approval-and-promulgation-of-air-quality-implementation-plans-indiana-nsr-reform-regulations","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E6-10679?publication_date=2006-07-10","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2006-07-10/E6-10679/mods.xml","not_received_for_publication":null,"page_length":8,"page_views":{"count":68,"last_updated":"2026-09-22 14:15:07 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2006-07-10/pdf/E6-10679.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2006-07-10","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2006/07/10/E6-10679.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-11-12T19:44:18Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":38824,"subtype":null,"title":"Approval and Promulgation of Air Quality Implementation Plans; Indiana; NSR Reform Regulations","toc_doc":"Indiana","toc_subject":"Air quality implementation plans; approval and promulgation; various States:","topics":["Air pollution control","Environmental protection","Incorporation by reference","Intergovernmental relations","Lead","Nitrogen dioxide","Ozone","Particulate matter","Reporting and recordkeeping requirements","Sulfur oxides","Volatile organic compounds"],"type":"Proposed Rule","volume":71}
